Spark Plugs on an 89

[pig4bill]

How about Autolites? I want to try a colder heat range than stock but Bosch doesn't make one.

Give it time.

UPDATE:

And that I did... My car has developed a crappy idle (could be due to many other things though) but more recently the car has been hesitating occasionally, and the problem has only been getting worse. These plugs are going in trash come tomorrow afternoon when my new plugs come in...

Any suggestions as to what I should get? NGK V power? or Bosch Supers?

I want some specific model numbers to go by when I place my order tonight. Thanks!

Bosch Supers W8LCR
although I've heard nothing bad about the NGK V power plugs (part no. ZGR5A)

while your gon change to bosch supers (you NEED supers, speaking from exp.) change your cap and rotor if you havent' done so....

How about Autolites? I want to try a colder heat range than stock but Bosch doesn't make one.

Autolite resistor 64.
Delco Standard R42XLS
Denso standard 3031
Accel 496
Champion 415
Motorcraft 436

One of these should work for you I think.

I have used Bosch and Champion in the M20 - both worked well for me.

Both copper - no platinum shit.

I've had bad experiences with Denso and Autolite.

Stick to Bosch.

[silversleeper]

Bosch it is then!

(NGKs werent in stock anywhere)

[RobertK]

You can get the NGK's through their website super cheap

[silversleeper]

I went ahead with NGK V Powers... holla!

[AdamF 88iS]

You'll have to take those end caps off of the NGKs, E30s dont use those connectors.

[silversleeper]

end caps were removed of course (they wont fit otherwise). I checked the spacing and they were on or about .028mm. i guess they are pre-gapped.

i agree, even my E36 M3 hated platinumplugs, bosche super coppers made the car run so much smoother. stick with copper. Remember just b/c it costs more doesn't make it better (thats my motto at least :) )

[arsevader]

Stay away from Champions like the plague. I wouldn't even use them in my lawnmower.

[silversleeper]

plugs are installed, and the car is running smoother. it could just be me, but i noticed that my car doesnt have anymore funky idle issues like it used to. i still have my occassional bouncing (650-950rpm) after some spirited driving, but that only happens for a few seconds before it stabilizes. high idle on cold starts still exist, but dont last as long anymore.

overall, i am pleased with copper, and wont ever go back to platinum, or iridium for that matter.
